Ceramic inlays, as well as composite resin restorations with or without a horizontal fiber post, seem to restore the fracture resistance of endodontically treated maxillary premolars to a level compared to that of intact teeth.

Some occlusal factors such as protrusive and non–working-side lateral interferences, as well as bruxism, are risk factors for the presence and development of noncarious cervical lesions.

Dental caries diagnosis is performed by most dentists from a Brazilian community using visual-tactile and radiographic methods.

The filling of deep, wide cavities with bulk-fill resin composites is appealing. However, some bulk-fill resin composites result in larger internal resin-dentin gaps than observed for an incremental-fill resin composite.

This case report discusses a full-mouth rehabilitation using direct composite resin and whether this technique is viable for a young patient with tooth erosion. The seven-year follow-up indicates that a conservative approach with an appropriate diagnosis of the patient is a good choice for achieving esthetics, function, and restoration longevity.

CLINICAL TECHNIQUE/CASE REPORT

A color repair technique can effectively correct an unsatisfactory restoration without replacement of the entire restoration, thus avoiding unnecessary removal of healthy tooth structure.

Clinicians should consider resin infiltration as a good treatment option of noncavitated proximal caries carefully.

CLINICAL RESEARCH

All 10% hydrogen peroxide systems showed similar whitening; however, bleaching strips and the prefilled disposable trays showed lower adverse effects.

The color of teeth whitened internally remains stable at one year of follow-up; tooth whitening also has a positive effect in terms of psychosocial impact.

LABORATORY RESEARCH

There may not be any significant advantage to the use of the new nanofiber composite resin restorative material (NovaPro Fill) compared to use of the hybrid composite resins (Filtek Z250, Esthet-X HD).

Some universal adhesives can achieve stable enamel bonding when applied with reduced application time.

When resin composites are submitted to bleaching procedures, immediate repolishing after the last gel application can improve color stability.

A composite resin stained by coffee or wine can be lightened to a clinically noticeable degree by some at-home tooth-whitening therapies.

Tooth bleaching reduces enamel microhardness and increases tooth-wear susceptibility. The use of remineralizing gels during bleaching procedures recovers enamel microhardness and reduces abrasive wear, increasing bleaching safety without compromising efficacy.

The new polishing systems for CAD-CAM ceramics including Vita Mark II, e.max, Suprinity, and Enamic can be good alternatives to reglazing, after clinical finishing, because the roughness and wear rate of both the ceramic and the opposing enamel will either not change or decrease.

There is no evidence of a clear advantage for using a polywave light-curing unit over a single-peak light-curing unit when photopolymerizing bulk-fill resin-based composites that use a combination of camphorquinone and germanium-based photoinitiators.
